Example of email_passwordless login provider

[serejke]

Hello, Web3Auth community!

I'm implementing an integration of Web3Auth into our DApp.
I've managed to integrate with custom Google auth without issues.

Now I want to implement the email sign up.
I've seen there is a email_passwordless login provider of the OpenLogin adapter.
But I cannot find any example of that provider, and what needs to be configured on the backend side and in the dashboard.

My goal is to have:

1. Email input on the /login page.
2. User enters an email and submits the form.
3. User received confirmation email.
4. User goes to the mail box and clicks the confirmation button.
5. User gets logged in with Web3Auth.

For what I see now, I can implement the Email verification:

1. Deploy a custom JWT verifier and provide custom JWKs on my app
2. Implement the email verification flow myself: send email with a temporary verification link which points to my app.
3. Once the user clicks the link, the app issues JWT token
4. Pass that JWT token into web3AuthCore.connectTo with loginProvider = jwt?

But I hope there is an out-of-the-box method from Web3Auth. In the demo it works as what I need, but I cannot understand how...

Hey,

1. Go to demo app source code.
2. Check how openlogin adapter is configured with custom verifiers.
3. Refer the doc for setting up openlogin adapter with desired login configuration in your case it is only email_passwordless.

@rinzler99 hey, I've just looked through all the demo code and I couldn't find any configuration for the email verifier.
Docs you provided barely mention email verification.

Could you point to the exact code/implementation or docs? Or maybe explain how the email flow works in a nutshell...
I appreciate your help a lot!

Hey @serejke

Please take a look at https://web3auth.io/docs/guides/auth0#enable-email-passwordless.

This is using Auth0 as an email login provider. And this is how we set up the Verifier https://web3auth.io/docs/guides/auth0#create-email-passwordless-verifier

And for custom JWT, use https://web3auth.io/docs/custom-authentication/byo-jwt-providers#using-jose to set up the Verifier.
